  • Flange Sealing Provided by compression of the liner between the valve body and the flanges. An elastomer o-ring, fitted underneath the PFA liner, allows proper flange sealing with warped flange faces or in vacuum applications.

    Sealing PrinciPleS

    Primary and Secondary Shaft SealingThe primary seal is formed by the flexible, spheri-cally molded liner, sealing against the matching spherically machined disc hub when compressed by the resilient elastomer backup liner. The PFA liner as well as the PFA shaft over-molding extends into the valve body itself. Tight compression is main-tained at the hub area and around the shaft by the resilient back-up liner combined with the flexible PFA liner, forming an independent secondary seal.

    Safety Sealing A third seal is provided by a graphite-filled PTFE safety seal, which provides force against the junction of the PFA liner and PFA over-molded shaft. This seal is constantly energized by a coil spring, and self compensates for tem-perature changes and wear.

    Upstream/Downstream SealingThe dense PFA body liner is flexible, and allows the resilient elastomer back-up liner to compress the spherically molded PFA liner into the spheri-cally machined shaft-disc with enough force to create a tight seal. This is in contrast to PTFE liners which are usually thick sinterings resulting in a stiff liner unable to give tight shut-off over a long period of time. The wide elastomer backup liner in the ACRIS rests in a machined body groove which is essential in providing tight shut-off for end of line service at full pressure. This has enabled the ACRIS to be used for pump and vessel isolation as well as other difficult services.

  • aPPlicaTiOnS ACRIS butterfly valves often replace other types of valves such as plug, ball and knife gates in non-traditional butterfly valve applications. The ACRIS can be used for end of line service and provide tight shut-off at the full rated pressure of the valve. ACRIS valves withstand the effects of all known corrosive fluids, and offer the purity required for ultra high purity applications. The superior pres-sure/temperature operating parameters are conser-vatively stated for reliable, full-term operation of the valve. Operated within these parameters, the ACRIS has a long, indefinite life in most applica-tions. ACRIS PFA lined butterfly valves can be used for pressures up to 150 psi and for industrial vac-uum (to 0.0002 PSIA). The ACRIS is also suitable on steam service (up to 280F) alternating with the flowing media.

  • CONSTRUCTION FEATURES The ISORIA elastomer-lined butterfly valve is part of a series of valves designed for the multitude of moderately corrosive applications throughout industry. Included in this series is the MAMMOUTH for large diameter (up to 140) and high pres-sure (up to 375 psi) applications. The ISORIA valve uses a spherically machined disc and a one-piece body that is totally isolated from the flowing media by means of the inner lining. A strong shaft-disc connection is provided by an
